Answer:
Linear expression
Step-by-step explanation:
If you have an expression with = sign, it becomes an equation
Without the = sign, it's just an expression
The formula for a circle's area is
. We are given an area of 38.465 square inches for a quarter of it.
Multiply this value by 4 to compensate for the quarter circle.


Divide both sides by pi (Note: I'm using the conventional value of 3.14)

Take the positive square root of both sides

The radius is 7 inches. Let me know if you have any questions, thanks!
Answer:
No solution.
Step-by-step explanation:
(1/12)^-2b * 12^(-2b + 2) = 12
1/12 is basically the same thing as 12^-1.
12^(-1 * -2b) * 12^(-2b + 2) = 12
12^2b * 12^(-2b + 2) = 12
12^(2b - 2b + 2) = 12
12^2 = 12
Since the answers don't match up, the answer will be no solution.
Hope this helps!
